Inducer-free expression systems are promising tools for biorefinery because they can reduce the reliance on inducers, reducing production costs and simplifying processes. Owing to their broad range of substrate structures and catalytic reactions, cytochrome P450s are promising biocatalysts to produce value-added compounds. However, unsuitable levels of cytochrome P450 expression could result in cell stress, affecting the efficiency of the biocatalyst.

The role of Box A of HMGB1 in producing γH2AX associated DNA breaks in lung cancer.

Sci Rep

January 2025

Center of Excellence in Molecular Genetics of Cancer and Human Diseases, Department of Anatomy, Faculty of Medicine, Chulalongkorn University, King Chulalongkorn Memorial Hospital, Bangkok, Thailand.

An ideal chemotherapeutic agent damages DNA, specifically in cancer cells, without harming normal cells. Recently, we used Box A of HMGB1 plasmid as molecular scissors to produce DNA gaps in normal cells. The DNA gap relieves DNA tension and increases DNA strength, preventing DNA double-strand breaks (DSBs).

A nanoemulsion was fabricated from Cananga odorata essential oil (EO) and stabilized by incorporation of Tween 80 using ultrasonication. The major constituents of the EO were benzyl benzoate, linalool, and phenylmethyl ester. Differing sonication amplitude (20-60%) and time (2-10 min) were assessed for effects on nanoemulsion droplet size and polydispersity index (PI).

2-Ethylhexyl diphenyl phosphate (EHDPP) is a replacement flame-retardant commonly found in several environmental matrices and human biospecimens. Although some adverse effects of EHDPP have been identified, the endocrine-disrupting effects of EHDPP and its key metabolites on the human estrogen receptor (ER) are largely unknown. Herein, we report for the first time that EHDPP, at concentrations found in the environment and humans, significantly promoted estrogenic activity and synergized with 17β-estradiol-induced ER transactivation.

This paper examines the motivations and experiences of older French-speaking men who relocate to Thailand driven by the desire for a more fulfilling and liberated lifestyle that contrasts with their experiences in their home countries. Through an analysis of video interviews with 31 expatriates available online, the study reveals a prevalent trend among these men to initially engage in short-term sexual relationships, enjoying the freedoms of Thailand's vibrant social scene. However, as they acclimate to their new environment, a significant shift towards long-term partnerships is observed, marking a transition from transient interactions to more meaningful connections.

Asian Perspective on Hepatitis B Virus and Hepatitis C Virus Elimination.

Viruses

December 2024

NKC Institute of Gastroenterology and Hepatology, Songklanagarind Hospital, Faculty of Medicine, Prince of Songkla University, Songkhla 90110, Thailand.

Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections remain significant public health challenges in Asia, affecting millions and contributing to substantial morbidity and mortality. The prevalence of these infections varies across the region, with factors such as vaccination coverage, healthcare infrastructure, and sociocultural barriers influencing the epidemiology of both viruses. The persistent burden of chronic HBV, particularly in older populations, and the evolving HCV genotype landscape highlight the need for targeted, region-specific strategies.

This study investigates the potential synergistic effects of extracts from (turmeric), (Arabica coffee beans), and (chili peppers) in reducing oxidative stress and inflammation, which are associated with metabolic disorders such as obesity, diabetes, and cardiovascular diseases. Using a systematic design of experiment (DoE) optimization approach, an optimal extract ratio of 1:3:4 (turmeric: coffee: chili) was identified. The efficacy of the extract combination was assessed through various antioxidant assays, inhibition of inflammation-related gene expression, and safety testing via the 3-(4,5-dimethylthazolk-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay.
